Here's an excerpt:

...An hour later Caiden awoke to find his friend had already left. Caiden's mom changed his wet diaper and Caiden watched TV on his belly until his brother got home.

"Hey, brother. How was the playdate with the neighbor kid?" asked Kyle as he set his bag down.

"Fine till da end." grumbled Caiden

"Oh, did you two get in trouble again?" inquired Kyle
Caiden just pointed to his butt in which Kyle pulled Cadien's diaper back to see the damage.

"Oooo....You gotta big whoopin. I might just have something to help with that." said Kyle as he reached into his pocket and pulled out a sucker.

Caiden's face lit up as he had forgotten all about the sucker that his brother promised earlier.
"Thanks big bro!" pounced Cadien as he gave his brother a big hug.

"Anytime stinkybutt." said Kyle as he hugged back.
